ABSTRACT
BACKGROUND: Methohexital is a short-acting barbiturate used for procedural sedation in the emergency department (ED). As with other sedatives, adverse effects with methohexital include excess sedation and hypotension, but this agent can also lower the seizure threshold. We report a patient who developed a generalized seizure after administration of methohexital. CASE REPORT: A 60-year-old man presented to the ED by ambulance with chest pain and shortness of breath. Paramedics had administered adenosine for supraventricular tachycardia without conversion before arrival to the ED. He had no history of seizures. His initial vital signs in the ED included heart rate of 189 beats/min with a supraventricular rhythm, blood pressure 137/108 mm Hg, respiration 22 breaths/min, and oxygen saturation of 98% on room air. It was decided to attempt synchronized electrical cardioversion, and methohexital 1 mg/kg (120 mg) was administered over 2 min for moderate sedation. Within 15 s of methohexital administration, the patient developed a generalized seizure that lasted for 90 s. After seizure termination, he was successfully cardioverted, returned to his previous baseline level of consciousness within 20 min, and discharged without further problems with a follow-up referral to neurology. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Methohexital is a short-acting barbiturate used for moderate sedation. Its adverse effects are unique in that it can lower the seizure threshold in some patients. Alternative agents for sedation should be considered in individuals with possible seizure disorders.

BACKGROUND: While the overall incidence of hepatitis A has declined markedly since the introduction of a vaccine, sporadic cases and outbreaks of the disease continue to occur. OBJECTIVE: Our aim was to evaluate the effectiveness of an electronic health record (EHR) provider alert as part of an outbreak-control vaccination program implemented in the emergency department (ED). METHODS: We conducted a retrospective study assessing the impact of a Best Practice Alert (BPA) built into an EHR to prompt providers when a patient was homeless to consider hepatitis A vaccination in the ED. Data were collected over three 6-month time periods: a historical control period, a pre-intervention period, and an intervention period. RESULTS: There were no vaccinations given in the ED in the historical period, which increased to 465 after the implementation of the BPA. During the implementation period, there were 1,482 visits identified among 1,131 patients that met the inclusion criteria. Of these, there were 1,147 (77.5%) visits where the patient either received the vaccine in the ED, had already received the vaccine, or it was not indicated due to the current medical issue. There were also 333 (22.5%) visits where the BPA was active for potential vaccination eligibility, but did not receive it in the ED. CONCLUSIONS: We leveraged an informatics tool developed within our EHR to identify high-risk patients and remind providers of the availability of vaccination in the ED. Using these tools enabled providers to increase vaccination efforts within our ED to help control the community-wide outbreak.
